The forward opened the scoring on 17 minutes. Martinez received a pass from Leandro Paredes 30 yards from goal, and the 22-year-old produced a stunning, buccaneering run that saw him beat three Mexican defenders before guiding the ball into the bottom corner.

Martinez doubled his, and Argentina's, tally five minutes later. A perfectly weighted through ball from Exequiel Palacios set away the striker who hit a a superb first-time finish to make it 2-0.

The Argentinians were awarded a penalty on 33 minutes for a Carlos Salcedo handball. Paredes stepped up and, although Guillermo Ochoa got a hand to it, fired home to triple the advantage.
